' warns GAIEI Application filed October 13, 1823. Serial No. 668,835.

even though the axial line of the conduit is out of perpendicular to thegate frame.

.n An illustrative embodiment of the invention is shown in theaccompanying drawing, in which Fig. 1 is a front elevation;

Fig. 2 is a vertical section on line 2, 2 of Fig. 3 is a horizontalsection on an enlarged scale on line 3, 3, Fig. 1;

Fig. 1 is a detail elevation drawn to a scale slightly larger-than thatof Fig. 1;

:42 Figs. 5 and 6 are detail plan views of the crank and the end of theshaft coacting therewith respectively.

As shown, the device comprises a frame casting 10 having uprights 11secured thereto and comprising angle irons. As shown,

particularly in Fig. 3, spacing members 12 are provided between theframe casting 10 and the angles 11 to provide waysin which the gateplate 13 may slide. For this pur pose, the edges 14 of the angles 12,are in vertical planes substantially tangent to the sides of thecircular openingin the frame casting 10, and the edges of the spacingmembers 12 are spaced away from said plane to provide the ways 15 abovereferred to.

The frame casting 10 is shown as formed with upwardly projecting arms 16to serve as guides for the gate plate 13 in its upward travel, and thespacing members 12 project upwardly to the top of said arms. The angles11, frame 10 and spacing members 12, may be fastened together as bymeans of bolts 17 passed through openings 18 in the casting 10, andcorresponding holes in the angles and spacing members.

To lift the gate plate 13 there is shown a vertical shaft 19, threadedas at 20, and journaled in an opening in the top angle frame member2-1secured to the upper ends of angles 11. Preferably gusset plates 22 areprovided to brace the angle between the top and side frame members. Toprevent vertical movement of the shaft 19 there is shown a casting 23having a recess coacting with an annular flange 2 1 carried by the shaft19,

Which casting 23,.is secured to the frame member 21, as by means ofbolts 25. To cause revolution of the shaft 19 there is shown a crank 26,the top of the shaft being given an elongated form, as shown in Fig. 6,at 27, and the opening 28 in the crank being formed to fit therewith.

To lift the plate 13 upon revolution of the shaft 19 there is shown abox 29 bolted to the top of the projection 30 from the plate, which boxhas an internally threaded opening to coact with the screw threads 20upon the shaft 19.

To preserve the alinemen't of the lower end of the shaft 19 as the plateslidesupwardly, there is shown a journal bearing 31 having a smooth boreadapted to receive the end of the shaft 19 and to slide upwardly thereonas the plate carrying the journal bearing moves upwardly. To limit thedownward movement of the gate a nut 32 is shown threaded upon the shaft19 and secured thereon, as by means of a cotter pin 33. It will be seenthat when the gate is lowered .so that the bearing 31 impinges upon thenut 32 a strain upon the crank 26 will cause the box 29 and the bearing31 to coact inthe" form of a lock nut, and when the shaft 19 isprevented from lifting by means of the annular flange 24:, the gate willbe held down against any tendency to lift. 7

To unite a conduit with the gate there is shown a collar 34, which maybe secured to the frame 10, as by means of rivets 35. To

make the gate self-centering, or, in other 0 words, to enable a conduitto be united there to, even though the axis of the conduit is notstrictly perpendicular to the plane of the gate, the opening in thecasting 10, which receives the collar 3 1, is given a flare so as tohave a frusto-conical inner surface 36.. If the rivets 35 are not set uptoo tightly before the gate is installed. a sledge hammer may be appliedto the edges of the collar 34, and the same may be caused to move in thefrusto-conical surface of the casting to assume a position with its axisat aslight angle to the plan'eof the gate, for the purpose abovereferred to. I

Minor changes may be made in the physical embodiment of the inventionwithout departing from its spirit.

I claim:

Awater gate comprising in combination a slightly frusto-conical pipeconnecting collar, uprights formed integrally therewith, upright guidemembers secured to said collar uprights, a cross plate connecting saidguide members at their top and a recessed hearing mounted midway saidcross plate, a gate mounted to slide along said guide members, said gatebeing provided with a centrally located elongated extension extendingupwardly therefrom, a screw threaded memher mounted at the top of saidextension, 2. plain bearing mounted near the center of said gate, anoperating shaft having an integral collar mounted in said recessedbearing and said plain bearing, and having a screw threaded portionengaging said screw threaded member, and means for rotating said shaft.7
